with traditional K, Carl extends height aspect, leaving ~same slot height - theres a 1/4 ellipse reflector within that enclosed portion- dunno if he gets a bit more LF-smoother mids or both - may be very subjective to builder/listener.

tough to do A-B switching of two Karlson as one not hooked up may emit energy from midbass into lower midrange.

Beta 12CX plays 'ok" in X15 (~2.1cu.ft. rar chamber)- could use lower Q although SP15A has enough mids to mask 'some' LF peaking- same story for Sigma 18 in a K-type with about 4cu.ft. rear chamber - also lower Le could help on the 18.

heres a near-slot by Lapaire - is this hinging just pressure distribution effects? - bottom green trace is towards floor.
